apatinib for advanced non-squamous head and neck cancer

Conditions: Head and Neck Neoplasms

Summary: in this study, the investigators try to evaluate the efficacy and safety of apatinib in advanced non-squamous head and neck cancer and to validate the correlative biomarkers.

there is no standard therapy for patients with advanced (unresectable, locally advanced, recurrent or metastatic) non-squamous head and neck cancer. apatinib is a novel vascular endothelial growth factor receptor 2 tyrosine kinase inhibitor, which has been approved for the treatment of patients with advanced gastric cancer refractory to two or more lines of prior chemotherapy. vascular endothelial growth factor is highly expressed in non-squamous head and neck cancer and its expression correlates with stage, tumour size, vascular invasion, recurrence and metastasis. in this study, the investigators try to evaluate the efficacy and safety of apatinib in advanced non-squamous head and neck cancer and to validate the correlative biomarkers.

* other malignancy within the past five years other than basal cell skin cancer, or carcinoma in situ of the cervix; * factors affecting the oral medication (e.g. inability to swallow, chronic diarrhea and intestinal obstruction); * major injuries and/or surgery =\< 4 weeks prior to registration with incomplete wound healing. patients who have received radiotherapy (except local palliative radiotherapy), chemotherapy, molecular targeted therapy =\< 3 weeks, or nitrosoureas/mitomycin chemotherapy =\< 6 weeks prior to registration; * patients with poor-controlled arterial hypertension (systolic pressure ≥ 140 mmhg and/or diastolic pressure ≥ 90 mm hg) despite standard medical management; * suffered from grade ii or above myocardial ischemia or myocardial infarction, uncontrolled arrhythmias (including qt interval male ≥ 450 ms, female ≥ 470 ms). grade iii-iv cardiac insufficiency according to new york heart association (nyha) criteria or echocardiography check: left ventricular ejection fraction (lvef)\<50%;
